We currently don't have one of those on roster who will be likely playing for us either this season or next. (Atiki's high-center build really makes him more of a 4 than a 5 at 6'9. His legs — while very athletic — are also very light.)
Isaac Johnson would be an invaluable pickup for us. He's still in his first year back from his mission, on a top-10 --possibly top-5-- most talented roster in the country. His utter lack of playing time right now says NOTHING of his D1 capability, let alone his ceiling.
Oregon's problem at the start of the season certainly was not depth & talent. It was inexperience & leadership. Two things everyone expected them to struggle with — just not to the degree that they did.
